The book "Earnest Class Destroyer" offers a comprehensive analysis of the Earnest-class destroyers that were in service with the Royal Navy during World War I. These destroyers were built by Cammell Laird and were designed for a speed of 30 knots to compete with foreign ships. Despite their high speed, the vessels were often uncomfortable in rough weather conditions and provided little space for the crew. Nevertheless, they proved their resilience and overcame numerous challenges during the war. The book draws on articles from Wikipedia and other free sources, providing an informative insight into the history and technical features of these destroyers.
